How to bulk rename files in a folder

Question

Hi,

I am requiring to bulk rename some folders in Power shell..

I am trying

rename-Item -Path  (get-childitem "\\server\Elucid\System Reporting\Maginus Reports\Chalgrove\Automated Reports\Current\").fullname -NewName (get-childitem "\\zoom-nas\Elucid\System Reporting\Maginus Reports\Chalgrove\Automated Reports\Current\").fullname + $today

Move-Item -Path  (get-childitem "\\servers\Elucid\System Reporting\Maginus Reports\Chalgrove\Automated Reports\Current\").fullname  -Destination "\\zoom-nas\Elucid\System Reporting\Maginus Reports\Chalgrove\Automated Reports\Archive"

How ever it is failing on the rename section.

The error message I am receiving is

Rename-Item : Cannot convert 'System.Object[]' to the type 'System.String' required by parameter 'Path'. Specified method is not supported.
At D:\server\MaginusScripts\Powershell\EmailChalgroveReports.ps1:8 char:20

• ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
• CategoryInfo : InvalidArgument: (:) [Rename-Item], ParameterBindingException
• FullyQualifiedErrorId : CannotConvertArgument,Microsoft.PowerShell.Commands.RenameItemCommand

Any help appreciated.

Hi,

You have to copy the items, not change the fullnames. And the '-Path' parameter doesn't accept an array.

$today = Get-Date -Format "MM-dd-yyyy"  
$source = '\\server\Elucid\System Reporting\Maginus Reports\Chalgrove\Automated Reports\Current\'  
$destination = '\\zoom-nas\Elucid\System Reporting\Maginus Reports\Chalgrove\Automated Reports\Current\'  
Get-ChildItem -path $source | ForEach-Object{   
    $newname = $_.BaseName + $today +$_.Extension  
    Copy-Item -Path $_.FullName -Destination (Join-Path $destination $newname)  
}
